The Lowy Institute

When Iran deterred shipping from the Strait of Hormuz following Operation Epic Fury, it sent shockwaves through global energy markets and exposed uncomfortable truths about Australia's dependence on maritime trade.  Jennifer Parker, a Nonresident Fellow at the Lowy Institute and former Royal Australian Navy warfare officer, joins Research Fellow Charlie Lyons-Jones to explain what a naval blockade means for the crisis. They also unpack Australia’s new National Defence Strategy and discuss why Australia’s surface combatant fleet is the smallest it's been since the 1950s.
